My translation:

The secretary of State Hillary Clinton said, the collaboration between China and the United States has resulted in more benefits than conflicts, but we must “turn nice words into concrete actions” to promote peace and prosperity on both sides.

美国国务卿克林顿说，中国与美国合作获得的利益要比冲突中多，但必须将“动听的言论转变成具体的行动”，促进双方的和平与繁荣。
